Initial Fill

CAUTION: The dispenser must be disconnected from the power source throughout the initial fill, except when 

specified in the instruction.

Step 1. Remove drip tray assembly and splash panel from the dispenser. Replace the drip tray.

Step 2. Connect the water source to the back of the dispenser.

Step 3. Pull the fill tube from the dispenser, remove the plug and connect it to the dispense nozzle.

Step 4. Set the Program Switch (near main control board) to the ON position. (On older models without program  

switch, set the Dispense Lockout Switch to the OFF position)

Step 5. Connect dispenser to the power source. Press and hold the dispense button for the dispense station that the  

tube is connected to for 10 seconds, until you hear the water valve turn on. (For Portion Control machines,  

press and hold the PLUS/STOP switch)

Step 6. Monitor the water bath fill level until water starts to trickle from the overflow tube. Then press the  

dispense button again to stop the fill process.

NOTE: The fill timer may time out before filling is complete. Press and hold the dispense button for 10 

seconds to start again if needed.

Step 7. Turn ON the refrigeration switch near the main control board. This will start the water bath pump circulation.

Step 8. Check water level in the overflow tube and top off the tank if necessary (Step 5).

Step 9. Disconnect the fill tube and allow excess water to drain into the drip tray. Replace the plug in the end of the  

fill tube and store back into the dispenser.

Step 10. Set the Program Switch (near main control board) to the OFF position. (On older models without program  

switch, set the Dispense Lockout Switch to the ON position)

Step 11. Replace the splash panel and drip tray.

Step 12. It will take several hours to create the ice bank required for full dispenser performance. During this time,  

some further trickling from the water bath is expected due to expansion caused by ice bank formation. While  

the refrigeration system is creating the ice bank, the dispenser may be readied for use as described in
